Didnt get much help on the Electronics forum so gonna try this on the motor side of the house.
Got a question for the experts here on the board. 2 days ago I go out to start the Ex after it was plugged in all night, ABS light comes on and stays on. Drove the truck maybe 100 feet and it goes out. This has happened every time I start it over the last couple of days, doesnt seem to matter it block heater is plugged in or not. The radio has also started to cut out for about 3-5 seconds and comes back on after. I have had the radio not come on for several minutes before in the past, almost like the truck had to warm up a little bit but it has been fine here lately. Temps here in MD have been in the low teens with wind chills in the negatives. Could the weather have anything to do with this?
Other than this the truck has been a little hard to start recently. Even with the block heater plugged in all night I have to crank the truck sometimes 3-4 times for what seems like a long crank cycle to me, I would guess anywhere from 6-10 seconds before it will finally start. Once it starts it has a very rough idle for 3-5 seconds and straightens up and acts fine. No DTC codes on my Livewire TS. I was thinking injector possibly. Last time I had a bad injector the rough idle was a lot worse than this.
Any and all help or inputs would be greatly appreciated

Looks like several different issues here. Your electrical problems as you suspect could be due to the cold. Electronics get kinda klakey to cold and heat extremes. Or you may actually have an issue only testing will tell.

Even you oil pressure issue could be cold related. During the winter a lighter weight oil is recomended, the cold can make it too thick for devices to work properly.

That said you could have a small oil leak in the high pressure oil system keeping you from reaching minimal operateing pressure.

Again only testing can tell for shure. There is a very good no start sticky on the 6.0 problems page.

Lord I shall lead them to the water but I will not try to make them drink

Thanks Danny. I thought about the HPOP as well. This morning the truck started great, plugged in all night, 18 degrees out started in about 3 seconds. Drove around a bit today and started fine until this evening after it had sit for about 4 hours. Key on, plugs heated and nothing!!!!! At this point it was almost 40 degrees outside, I cranked it for about 15 seconds this time. Turn key off and plugs cycle again and it starts in about 3 seconds again. I did notice that once the truck does finally start the oil pressure and fuel gauge on the dash go back to zero and in a second or so they come up to normal pressures on the dash. Same radio issues as described above but the ABS light has gone out now. Called my mechanic to get it into the shop and waiting a call back. I think I may have a wiring gremlin. Seriously considering a FOR SALE sign on this and getting a 6.4
